The Nebular Variables focuses on the nebular variables and their characteristics. Discussions are organized by type of nebular variable, namely, RW Aurigae stars, T Orionis stars, T Tauri stars, and peculiar nebular objects. Topics range from light variations of the stars to their spectroscopic and physical characteristics, spatial distribution, interaction with nebulosity, and evolutionary features. This volume is divided into four sections and consists of 25 chapters, the first of which provides general information on nebular variables, including their stellar associations and their classification into three distinct groups: RW Aurigae, T Orionis and T Tauri variables. These three groups of nebular variables are examined in more detail in the chapters that follow in terms of their light variations, spatial distribution, interaction with nebulosity, and spectroscopic, physical, and evolutionary characteristics. Visual and photoelectric light curves, mass loss determined spectroscopically, luminosities, and stellar radii are considered. The book also explores the possibility that some of the nebulae associated with certain nebular variables have evolved from a protoplanetary disc of material consisting of both gas and solid matter. Peculiar nebular variables such as the long period variable R Aquarii, Herbig-Haro objects, symbiotic variables, and infrared stars are analyzed as well. This book is written primarily for students and teachers of astronomy.
